Ah, ok. Hair splitting time, then. I took transmission on the American side as meaning gearbox. I did mention seized bevel box, but what the heck.
You've got the reply now, Dan..!
I really should have said "drivetrain"
There we go again, two countries separated by a common language.
After being on here several years, I should have said gearbox instead of transmission.
At work I'm now typing aluminium rather than aluminum, just to screw with people.

And as far as I can remember, there was only one gearbox issue and that was a rear tailshaft seal. At least posted on the forum.
